Adam, I found this pic at L.H. Are these the 299's you have access to?

Lucky guy!

hi v.o.t. ,

those are indeed the drivers i have access to...
don't own them but they can be made available
for conversion into 2 or 3 way systems.

chap in question has means to match the drivers
according to frequency response etc. same fellow
has solid folder of official altec box plans - hope
to have a good read at some point.

fellow with the model 19's is local number one
for valve guitar amp repair - also sees all sorts of
hifi esoterica - mean to post some pictures at
my picasa photostream; lovely guy too.....

thanks for checking in, all thoughts welcome,

cheers,

a
